Operation of Cal-Pro Zilmet range:

The CAL-PRO range of Expansion Vessels is specifically designed for domestic and commercial unvented central heating systems.

The purpose of these vessels is to accommodate the increased liquid volume which occurs during system heating in an Unvented Circuit. A pressurised membrane allows ingress/egress of the liquid only during periods of heating / cooling.

The correct size of vessel must be considered prior to installation and installed by appropriately trained engineers.

Installation Siting for Cal-Pro Zilmet range:

The Expansion Vessel must be fitted to the Return Side of the Central Heating System and in such a way that there can at no time be an obstruction between the vessel and the system.

The orientation of the expansion vessels Water Connection should be downwards to avoid risk of sediment ingress or other debris from the system. Some provision for the prevention of air ingress into the vessel must also be made as this will degrade thevessel very quickly.

Adequate provision for the mounting of the expansion vessel must be made by the installer and a suitable bracket or other mounting method used. A range of suitable brackets are available as accessories.
